T RANSFERRING BEVEL AND TRY SQUARE.

SPECIFICATION forming part of Letters Patent N 0. 699,261, dated May 6, 1 902. Application filed February 11, 1902. Serial No. 93,581.- (No model.)

To all whom it may concern:

Be it known that I, ORvIs VALLIER, a citizen of the United States, residing at Watertown, in the county of Jefferson and State of New York, have invented certain new and use ful Improvements in Transferring Bevel and Try Squares; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in combination protracting transferring bevel and try squares, designed especially for use in setting knives on sticker and shaper heads; and it consists in the provision of a frame or receiver, between the longitudinal sides of which a protracting arc is disposed bearing a scale,while between the faces of the frame is pivotally mounted a bevel setting-tongue with indicating-pointer traveling over the surface of the protracting arc, the curved edge of said pointer being adapted to actuate a cam projection on the edge of a pivoted transferring-arm, thereby automatically adjusting the arm to the desired angle as said tongue is turned upon its pivot. v

To these ends and to such others as the invention may pertain the same'consists, further, in the novel construction, combination,

and adaptation of parts, as will be hereinaf-. ter more fully described, and then specific-- ally defined in the appended claims.

My invention is clearly illustrated in the accompanying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings simi lar letters of reference indicate like parts in the several views, in. which Figure 1 is a plan view showing the device with the tongue and cam carrying pivotal arm adjusted at'a certain angle. Fig. 2 is a View showing the device adjusted for use as a trysquare. Fig. 3 is an end view of the device with the parts shown in the positions illustrated in Fig. 2.

Reference now being had to the details of .withthe longitudinal edge of the frame.

the drawings byletter,A designates the frame, which is made up, preferably, of two skeleton plates spaced apart, the lower plate being provided with a protracting are A between its longitudinal sides, on which there is a scale. Disposed between the longitudinal edges of the upper plate is a curved keeper B, between which and the inner face of said are the pointer O is guided. Said pointer is formed at the end of an angled tongue D, which is pivoted at D on an adjusting thumb-screw E, which is fitted in registering apertures in the two plates of the frame, the wall of one of said apertures being threaded to engage the threads of the thumb-screw. Said tongueD has'an extended shank portion F, the inner edge of which is utilized to determine the angle which isdesired to be transferred or laid off upon a pattern. The pivotal end of said tongue has a cam-shaped or undulating edge, as seen at G, against which the cam H,

integral with the arm K, is adapted to 0011. tact. Said arm K is pivotally mounted on an adjusting thumb-screw N in registering apertures in the arm and plates of the frame, and by means of said thumb-screw the arm may be held'in an adjusted position to lay off the desired angle.

In dotted lines, Fig. 1, I have shown a pattern 'M, having an inclined end M and a straightedge O, the latter being in contaIct n determining the angle to be transferred the shank portion F is moved so that its inner longitudinal edge will contact with the inclined end M, and in such movement the outer cam edge of the tongue will bear against the cam H and will throw the'arm K out from the frame, so that the outer edge of said arm will assume a position forming an angle with the adjacent longitudinal edge of the frame equal to the angle between the inner-edge of said shank portionF and the'adjacent edge of the frame. I have also shown in dotted lines at T a transferring member on which the angle is laid 0E and by means of the guide-block S adj ustably held on said member, forming a straight edge. The transferring member may be held against any object to which the angle is to be transferred.

It will be observed that the device is automatic as far as laying off the angle on the transferring member as the tongue is moved to the required angle, and by holding the cam on the pivoted arm in contact with the edge of the indicating-pointer said arm is moved with same.

When the arm and shank portion of the tongue are to be used as a try-square, the arm is swung into the position shown in Fig. 2, in which said arm rests in a groove in the longitudinal edge of the frame between the two plates thereof, and the shank portion F assumes a position, as shown, at right angles to the edge of the frame.

The utility of a device made in accordance with my invention will at once be apparent, as it may be used in transferring angles from patterns to any objects, for setting knives on sticker or shaper heads by simply setting the indicating-pointer on the scale, which will antomatically throw the arm held against same to the required angle.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is

1. A transferring bevel and try square, comprising a frame having an arc with scale thereon, an indicating pointer or tongue pivotally mounted on said frame and having a shank portion designed to form various angles with the edge of the frame, a pivotal arm carried by the frame and designed to be actuated by said tongue as it is moved over said scale, as set forth.

2. Atransferrin g bevel and try square, comprising in combination with a frame, an arc with a scale formed thereon, an angled tongue pivotally mounted on said frame and having a shank portion designed to be held at various angles to the side of the frame, a pivotal arm, mounted on the frame and having a cam projection which is designed to contact with the curved edge of the end of the tongue, as the latter is passed over said scale, whereby an angle between said arm and the adjacent edge of the frame is laid ofl, equal to the angle between said shank portion of the tongue, and the opposite edge of the frame from that carrying the pivoted arm, as set forth.

3. A transferring bevel and try square, comprising a frame made up of two plates, spaced apart, an arc with a scale formed thereon intermediate the longitudinal edges of the lower plate of the frame, an angled tongue pivotally mounted on the frame, one end of said tongue formed into a pointer which is adapted to be passed over said scale, a shank portion of said tongue extending laterally from the frame, a pivoted arm carried by the frame and having a cam projection against which the inner curved or cam outline of said tongue is adapted to bear whereby said arm is moved in unison with the shank of said tongue, as set forth.

4. A transferring bevel or trysquare, comprising a frame made up of two skeleton plates spaced apart, an arc with a scale thereon, a keeper on the upper plate spaced apart from said are, an angled tongue pivoted between said plates of the frame, and having one end formed into a pointer which is adapted to be passed over said scale, an arm pivoted between the plates, and having a cam projection which is adapted to be in contact with the outercam-face of said tongue,whereby the arm will be moved automatically as said tongue is moved over the scale, as set forth.

5. In combination with the frame, made up of two skeleton plates spaced apart, a pivoted arm mounted between the plates and adapted to rest in a space intermediate the plates and in a position with its outer longitudinal edge parallel with the adjacent edge of the frame, an angled tongue with integral shank portion, pivoted between the plates, and designed to be held by a cam projection of said arm, at right angles to the longitudinal edge of the frame, as set forth.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

ORVIS VALLIER.
